Air conditioning - general information
Turn off the air conditioning when starting the
vehicle to reduce the starter motor load.
The air conditioning system works only when
the engine is running. Moisture is removed from
the incoming air during the air conditioning
process and this assists the de-misting of
windows.
NOTE: When operating the air conditioning
system in conditions of high humidity, extracted
water can cause a build up of ice in the system
which will restrict air flow. In such conditions the
air recirculation lever (F) shown on page 24
should be set and retained in its recirculation
position.
Both during and after use, it may be noted that
water drains from the air-conditioning system
below the vehicle and this is normal.
Air conditioning systems consume energy and
increase fuel consumption. It is good practice
to use the air conditioning system sparingly.
It is beneficial to ventilate a vehicle which has
been standing in extremes of heat, by first
opening the windows and then operating the
heater blower at its maximum for a few minutes,
with the temperature control set to cold, before
closing the windows and turning on the air
conditioning system.
The air conditioning system should be operated
for a minimum of 5 minutes each week
throughout the year. This lubricates the internal
components and helps to maintain the seals in
the system and prevent loss of refrigerant.
WARNING: The air conditioning
system uses environmentally friendly
(R134A) refrigerant and no alternative
must ever be used. The air conditioning
system must be serviced by trained
technicians familiar with such systems using
the correct specialised equipment.
Special care is particularly required when
handling refrigerant gas, so no part of the air
conditioning system or its pipes should be
disconnected by untrained personnel.
CAUTION: In most countries is an
offence to deliberately release
refrigerant gas to the atmosphere.
Moisture and foreign particles in the refrigerant
will have an adverse affect upon the satisfactory
operation of the air conditioning system. Always
ensure the receiver dryer is replaced by a trained
technician at the intervals specified in the
maintenance section of this handbook.
The air conditioning compressor belt driven by
the engine must always be maintained at the
correct tension. If the system fails to function
correctly and the compressor drive belt is in
good condition and correctly tensioned, seek
the help of a trained technician.
